Joliet man held in slaying of business partner

Joliet Police today arrested a 28-year-old Joliet man in the robbery-murder of his business partner.

Police Chief Mike Trafton said the suspect made self-incriminating comments while being questioned about the slaying of his partner, Sean D. McGin, 39, who was shot to death behind the gym they operated on the city's east side.

Trafton said the suspect lured McGin to the rear of the Joliet KO Zone Gym on the 200 block of East Cass Street with the promise of a non-existent quantity of cocaine.

He said police are pursuing murder and felony theft charges against the suspect in custody and are searching for at least two co-conspirators in connection with the fatal shooting, which occurred about 11 p.m. between Scott and Collins streets.

Trafton, crediting "outstanding police work by all involved," said the suspect admitted during questioning that he "never had the intention to deliver" the drug and that he had removed the drug payment from McGin's car, but blamed a co-conspirator for shooting McGin twice.

Police, responding to the 11:05 p.m. call, found McGin was unresponsive. The Will County Coroner's office pronounced McGin, of the 1000 block of McKinley Street in Lockport, dead at 12:50 a.m. Friday.
